KAMINO - The Confrontation - Star Was: The Force Unleashed 2
I hope you not only love Double Jump Dash but are really good at it because that is pretty much all this level is. Start but working your way around the interior hall talking out enemies as you go.
HOLOCRON - Disintegration saber crystal
When you get outside you will see the saber crystal in front of you on a half circle platform. Before you drop down Force Grip the crate that is beside you on this high area and move in front of the platform. Then hop down and use the crate to get Holocron.
ACHIEVEMENT - Amplified [10/Bronze]
There are large energy coils in this next area. To get the achievement you need to Grip throw 10 Imperials into them.
HOLOCRON - Shock saber crystal
You'll do yet another drop down into a room with a ton of Spiders. After taking them all out the saber crystal is right in the room.
First we need to clear the ground area. We are going to have Jumptroopers, Sith, Terror, everyone is coming to the party. Watch your back and eliminate people as soon as they arrive with grapples.
ACHIEVEMENT - Top of the World [10/Bronze]
For this achievement you need to make it all the way to the top without falling once. One fall and its restart mission. This is not a fun achievement with the lack of precision in jump dashing. Always try to end your dash at the widest part of any area and jump a little early. I died so many times to simply falling off the edge when I was no where near the edge. Work your way up moving the large long circular sections up, down, left or right as needed. About halfway up you'll come to a door and you need to Force Grip open.
HOLOCRON - Experience
Then in the final section you'll get to a series of rotating circle platforms with glass chambers on them. There is pretty much a Terror Trooper on EVERY SINGLE ONE OF THESE PLATFORMS. At the top level you'll see the yellow Holocron inside one of these. Smash it open to get the last Holocron.
KAMINO - The Confrontation Collectibles
Prepare yourself for the most boring boss battle in the history of the world. 90% of this battle is Vader jumping away from you, pulling in a bunch of clones, you Mind Trick them to fight Vader, then you beat on Vader. Get a button sequence and then REPEAT. A LOT. An insane number of times. The only times I died was from bad jumps.
At the end pick a path. Dark or Light. If you want both achievements and both endings, as soon as you pick one and get the achieve drop to dash and reload and you'll be right at the decision.
